LGTM.

This kinda made me wonder if all those URLBuilder methods should provide variadic url.Value params in v3.

Yes I understand that would mean breaking notifications.URLBuilder, but since we've decided to break some interface in v3 we might as well do this.

That's a good point. However, do we have a use case (now or planned for the near future) for URL values in other methods that don't have them already? Exposing these before they're needed is counter-intuitive IMO.

We don't actually, no. I was merely thinking out loud just in case the topic comes up.
